Title: Improvements in or relating to fluid pressure valves
IPC: G05D16/06
Filed: 1921-12-19
Abstract: 194,429. Martin, J. B. Dec. 19, 1921. Pressure-regulating valves.-A pressure-regulating valve of the kind in which the expansion outlet of the valve is isolated from the valve seating so that the valve seating is maintained substantially at the temperature of the passing fluid has the valve 1 formed with an elongated head 2 loosely accommodated in a cylinder 3 so as to leave a constricted annular space 4. Specifications 1572/98, 25206/09, 746/14, and 16204/15 are referred to.

Abstract: 920,101. Load handling trolleys. LLOYD'S PACKING WAREHOUSES (HOLDINGS) Ltd. Oct. 5, 1961 [Oct. 5, 1960], No. 34081/60. Classes 78 (1), 78 (3) and 78 (4). A wheeled load-handling trolley consists of a base 1, a folding ramp 16 attached thereto, a raisable platform 13 suspended from corner posts 7, 8 (not shown) and 9, 10 on the base, and a hinged flap 19 carried by the platform at the end thereof remote from the ramp 16, so that loads may be run on to the platform by use of the ramp 16 and unloaded into an aircraft with the platform at a higher level, using the flap 19 to bridge any gap between the platform and the aircraft. The platform raising mechanism may be housed as shown in the corner posts comprising, e.g. a motor to drive the pulleys 25 and 26, or rams 21, 22 to raise these pulleys-in which case a cable attached at one end to the base and at the other to the platform is wrapped round each pulley-or rams which raise the platform directly. Alternatively, rams not carried in the posts may be employed to raise and the posts merely to guide the platform: such rams may act on a lazy-tong lever system. In handling conventional loads the platform is raised equally at all four corners. In some forms for such use the platform is detachable from the corner posts for pre-loading and/or its surface fitted with means such as a rollerway for conveying goods therealong. For handling vehicles, the platform may be formed with wheel guides and in use is raised only at the end remote from the ramp 16 so that the platform itself provides an extended rampway up which the vehicles may be driven from ground to loading level.

[Classes 83 (ii) and 83 (iv)] [Also in Groups XI and XL (a)] Coiling; mandrels.-A method of preparing an electrode for an electric discharge device comprises winding a tungsten wire 3 on a mandrel consisting of a tungsten conductor 1 and a molybdenum wire lying side by side, to form loops in contact with more than half the perimeter of the tungsten conductor. The coil is then set by heating in hydrogen to 1500‹ C. and the molybdenum dissolved out. The coil is then charged with activating material. As shown, the tungsten conductor 1 is of larger cross-section than the molybdenum wire 7, but the wire 7 may be of equal or larger diameter than the wire 1, in which case the wire 3 is squeezed inwards at 6 to engage the wire 1 for more than half of its perimeter.

Abstract: 1347723 Explosive jointing BURNDY CORP 26 July 1971 [29 July 1970] 34976/71 Heading B3Q [Also in Division H2] A connector device has an opening for receiving a conductor and associated with it an explosive-containing member which expands on detonation of the explosive to bring about the reduction of the effective cross-section of the opening and grip the conductor received therein. In Fig. 6 conductors 17 are inserted into opposite ends of conductive sleeve 10 having central wall 11. Substantially tubular shells 14 containing explosive are wound around each inserted conductor end and the ends of sleeve 10 are stopped with screwed in plugs 26. Shells 14 may also be wound round plugs 18 abutting central wall 11. A single tubular shell may be wound round both conductors (Figs. 8, 9, not shown) a central portion of the shell being inserted into a cavity in a central plug. Detonation expands the shells within sleeve 10 to grip the conductors. As shown in Fig. 10, detonation of explosive in shell 61 expands it to cause hooks 58 to grip conductors 55. For joining conductors 32 each having a central reinforcing cable 31 (Fig. 12) tubular explosivecontaining shell member 33 is wound round the ends of conductors 32 and round the exposed ends of cables 31.

As shown sleeve 30 is turned in at ends 37 prior to detonation. In a further embodiment (Fig. 15) detonation of explosive in shell 81 causes lever 78 to grip securely conductors 70, 71 which may be of widely different diameter. Detonation may be electrical (Fig. 7, not shown) or by a plunger (Fig. 9, not shown).

Title: Clear air turbulence detection

Abstract: 1,093,509. Electrical detection of air turbulence. LITTON INDUSTRIES Inc. Aug. 4, 1966 [Aug. 4, 1965], No.35064/66. Heading G1N. The detection of clear air turbulence to prevent damage to high-speed, high altitude aircraft, is effected by measuring changes in more than two variables, e.g. ram air temperature, i.e. air temperature under dynamic conditions, ground speed, angle of drift or cross track velocity of the aircraft, which are affected by the presence of turbulence. In the embodiment, the variables are detected by means 10, 22, 34 e.g. a thermocouple for ram air temperature. The output signal from each detector is then fed to a differentiating circuit 12, 24, 36, whose output signal is, in turn, fed to a level detector 14, 26, 38 which transmit signals only if the input signal exceeds a predetermined value. Simultaneously the differential signal is fed to an integrator 16, 28, 40, together with the output from the level detector, such that when there is no signal at the output of the detector the integrator is set to zero. Thus when the differential signal exceeds the predetermined value of the level detector, it is integrated in means 16, 28, 40 and fed both to a meter 18, 30, 42 from which the value of the variable can be read off and to a further level detector 20, 32, 44 which generates a signal if the output of the integrator exceeds a predetermined value. The signals from the detectors 20, 32, 44 are then applied to the input of a gate 50 which is adapted to generate an output signal when at least two of the input signals are present to operate an alarm e.g. horn, bell, light 54. The output of the gate is connected to the alarm through a lock and reset circuit 52 which continues to actuate the alarm until it is turned off manually.

[Also in Division C3] Compositions containing graphite crystallites with a high degree of parallelism of their c-axes (well oriented) are made by forming a dispersion of graphite crystallites in a viscous pasty, or plastic medium and subjecting this dispersion to the action of a shear force, or a shear force in combination with a compressive force. The viscous medium is heated to a temperature at which its viscosity allows the crystallites to move only under conditions of shear. The shear forces may be applied by rolling (either on heated rollers or with radiant heating) preferably in at least two directions at right angles, or by passing through a die. The viscous material is used in an amount from 5-90% by weight of the graphite and may be P.V.C., polyaciylates, polyvinyl aromatic hydrocarbons, polyvinyl esters, cellulose esters and ethers or a wax. The viscous medium may be carbonized by heating to 600-800‹ C. preferably out of contact with oxygen.

Abstract: 338,371. Girod, P., (Assignee of Franchini, A.). Aug. 27, 1929, [Convention date]. Furnace details.-An electrode for an electric furnace or an electrolytic vat is adjustably mounted by means of two collars, the distance between which can be regulated as desired. One collar, which may form part of a plate 1 secured to the furnace or electrolytic vat supporting several electrodes, is fixed and the other collar 4 is movable,. Rings 2 and 3 attached to the plate 1 serve as guides and shields for the electrode. The collars are connected by some device which allows the distance between them to be adjusted, such as the toggle-links 11, screw 12, and handwheel 13. The collar 4 is placed in its extreme position, the electrode adjusted in it and secured by a set-screw 6. The electrode is then fed forward as required by means of the handwheel 13 as far as the toggle will allow. The electrode is then clamped to the collar 1 by a screw 5. the screw 6 loosened, the collar 4 again set at its extreme position, and the electrode again secured to it. The electrode may consist of a number of cylindrical blocks 18.
